Windows HTTP & Print Spooler Port Conflict Resolution: This script ensures that port 80 remains open for other applications by moving the default Windows Print Service to a different port.

.SYNOPSIS
   Windows HTTP and Print Spooler Port Conflict Resolution Script

.DESCRIPTION
   This script resolves port conflicts between Docker/Web services and the Windows Print Spooler
   by reconfiguring the HTTP service to use port 5000 instead of 80. This allows both printing
   and Docker to work simultaneously.

.NOTES
   - Must be run as Administrator
   - Creates a log file in Downloads folder
   - Will forcefully stop and restart printing services
   - Recommended to save any open documents before running

.INSTRUCTIONS
   1. Save this file as Fix-PrinterConflict.ps1
   2. Right-click the file and select "Run with PowerShell"
   3. If prompted, choose "Yes" to run as Administrator
   4. Check output for any errors
   5. Test both printing and Docker after completion
